Signal Processing Module

This software layer analyzes the return signal of each target according to application-specific alarm
thresholds for target size, range, and speed. Only those targets that exceed the predefined thresholds
in user-selected ranges would trigger an intrusion alarm. A programmable alarm-condition counter
provides a simple but effective means of preventing false alarms.

Antenna Module

The choice of antenna is generally dictated by beam geometry (elevation and azimuth beam
angles and range). In addition to those defined in the standard configurations (SR 0303, SR-3030 &
SR-4505), other beam geometries can be achieved using custom-designed antenna.

Communications Module

Apart from the basic function of transmitting alarm signals, the bi-directional communication layer is
also used for the direct control of internal operating parameters during installation and setup. In
addition, the embedded micro-controller can be remotely reprogrammed after installation, to cope
with any changes that may arise in the overall security scheme.

Environmental Layer

This hardware layer includes the housing, connecting, mounting, and aiming arrangements
according to the requirements of each end application.

All K&G Spectrum radar sensors are completely weather sealed, with lightning protection on all
input/output lines.

Reliability Features

Hardware and software elements are embedded in the K&G Spectrum radar sensor for automatic
self-test to be performed at regular intervals. The self-test procedure is integrated with, but
transparent to, normal operation. This self-test, in conjunction with a communication protocol that
includes "heart-beat", allows complete system health to be continuously monitored.

Installation and Alignment

K&G Spectrum radar sensors are designed for easy installation with supplied mounting kit.

Optical or video alignment (aiming) aids are available for aiming the search beam accurately
and rapidly at the intended area of coverage.

Sensor Verification

Area of coverage for each sensor can be easily verified and alarm threshold adjusted by a single
operator in a "walk test" while monitoring sensor response using a hand held K&G Spectrum
wireless decoder unit in conjunction with a temporarily attached wireless transmitter.
